NVIDIA: Crypto "Doesn't Bring Anything Useful"

An interview on The Guardian talks tech with Michael Kagan, the chief technology officer at NVIDIA. The headline quote from the story is Kagan's assertion that cryptocurrencies do not "bring anything useful for society," despite how crypto-driven demand for NVIDIA GPUs has done wonders for the company's bottom line for years. In contrast, he speaks positively about ChatGPT, saying AI is actually useful:
The first version ChatGPT was trained on a supercomputer made up of about 10,000 Nvidia graphics cards.

“All this crypto stuff, it needed parallel processing, and [Nvidia] is the best, so people just programmed it to use for this purpose. They bought a lot of stuff, and then eventually it collapsed, because it doesn’t bring anything useful for society. AI does,” Kagan told the Guardian.

“With ChatGPT, everybody can now create his own machine, his own programme: you just tell it what to do, and it will. And if it doesn’t work the way you want it to, you tell it ‘I want something different’.”
